Abstract

The μ-RWELL is a single-amplification stage-resisitive MPGD. The amplification element is realized on a polyimide foil micro-patterned with high density blind-holes (wells) and is embedded through a thin resistive film in the readout PCB. The introduction of the resistive layer suppresses the transition from streamer to spark giving the possibility to achieve large gains (> 104). As a drawback the capability to stand high particle fluxes is reduced. To avoid such a limitation different resistive layouts have been designed. The study of the performance of such layouts done at PSI, together with the measurement of the space resolution for orthogonal and inclined tracks performed at CERN are presented in this work.
